BALANCE ANI) FASTENER FOR WINDOW-SAS-I-I.

Specification of Letters Patent No. 15,939, dated October 21, 1856.

To all whom t may concern Be it known that I, VALTER W'ORTHEN, of Danville, in the county of Rockingham and State of New Hampshire, have invented a novel and useful Improvement in IVindow-Sash Balances and Fasteners; and I hereby declare that the following specification, in connection with the accompanying drawings and references thereon, constitute a lucid, clear, and eXact description of the construction and use of the same.

In referring to said drawings, Figure l denotes an elevation, or inside View of the window frame and window sash with my fastener and balance attached; Fig. 2, transverse and vertical section on line A, B;

Fig. 1, showing the parts beyond, one of the sashes being removed so as to fully show the recess L, and pin or catch K. Fig. 3, is a longitudinal and vertical section of the whole frame and the front sash therein on line C, D, Fig. 2, and showing the parts beyond. Fig. 4, is a perspective view of the spring balance, and fastener C as connected with its lever D, both being disconnected from the window sash. Fig. 5, is an edge view of the window sash showing my spring balance and fastener attached thereto. Fig. 6, is a section view of this sash disconnected from the window frame on line E,.F. f Invention-The nature of my invention consists in so constructing, and operating one single spring as within described that it will answer both to balance the sash in any desired elevation, and so that it will effectively fasten the sash when the'window is closed, as will be hereafter seen.

Construction-To enable persons skilled in the art to which my invention appertains to construct and carry out the same, I will i describe it as follows: I construct a window spring seen at C, Figs. 3, 4, 5, and 6, with a slot formed in its upper part as seen at E into which the head F of the lever D is placed to press this spring C, back into the sash to disconnect the spring C from the pin K, which is Xed to the casing in the recessL, formed in the side of the casing seen at Fig. 2. The lever D, may be made of brass or any other proper metal as seen in the several gures of the drawing, and turning on the pin J which passes through it and thefstile of the sash, there is to be a mortise formed through the sash B to receive the lever D, through which one end of it projects suiicient to be operated by the hand, while the opposite end has a head formed on it as seen at F to connect it with the spring C, as seen at Figs. 3,4, 5 and 6.

I form a hole through the spring near its upper end as seen at G Figs. 3, 4, 5 and 6 for stopping or fastening the sash by catching on to a pin K or its equivalent firmly fixed in the side, or grooves P and Q, of

the window frame seen at Figs. 2 and 3. The springs C are fastened to the sash B by two wood screws seen at H, H, after a proper recess has been formed in the sash B for them the springs C to be placed and to freely slide in or operate in.

The outward pressure of the projection `D, pressing it upward so that it will both disconnect the spring or fastener from the pin K and raise the window as may be desired. By placing the fingers upon the top of the lever D in the upper sash and pressing it down, the spring C will be disconnected from the pin K and the sash lowered, as may be desired and there remain until it is desirable to again raise or close it. which will be readily understood.

It will be observed that the curve formed in the spring C will cause them to ride over the pin K in the recess L, until the hole Gr, comes over the pin K, when the spring C will instantly press outward allowing this pinto pass through the hole G in the spring C, and thereby hold or fasten the window, it being wholly self operating Window the lever D must be pressed so as both by one spring, constructed arranged to disconnect the spring C from the pin operated essentially in the manner and for K When the sash can be readily moved as the purposes fully set forth.

may be desired. WALTER WORTHEN. 5 What I claim as my invention and desire Witnesses:
